Flatlands

Map showing the approximate location of the Flatlands on the continent of Essos.

The Flatlands is a region on the continent of Essos, located to the east of Westeros beyond the Narrow Sea. The Flatlands is a fertile area of open fields and plains, located around the Free City of Pentos and responsible for feeding it. Many magisters and nobles of the cities have estates on the Flatlands.[1]

In the A Song of Ice and Fire novels, the Flatlands are bordered by the upper reaches of the River Rhoyne to the east, the Velvet Hills to the north and the Golden Fields to the south-east. The Dothraki have easy access to the Flatlands and find riding across it easy, so Pentosi nobles pay them heavy tribute so as to ensure they do not loot or sack any of the estates or villages in the area.

The Flatlands used to be part of the southern kingdom of the Andals before they fled to Westeros several millennia ago.
